Question

Match the column I with column II and mark the appropriate choice.

Column I Column II

$\left(A\right)I{F}_5$	(i) Square pyramidal
$\left(B\right)I{F}_7$	(ii) T-shaped
$\left(C\right)Br{F}_3$	(iii) Pentagonal bipyramidal

• A. $\left(A\right)\to \left(iii\right);\left(B\right)\to \left(ii\right);\left(C\right)\to \left)\right(i)$
• B. $\left(A\right)\to \left(ii\right);\left(B\right)\to \left(i\right);\left(C\right)\to \left)\right(iii)$
• C. $\left(A\right)\to \left(i\right);\left(B\right)\to \left(ii\right);\left(C\right)\to \left)\right(iii)$
• D. $\left(A\right)\to \left(i\right);\left(B\right)\to \left(iii\right);\left(C\right)\to \left)\right(ii)$

Answer 1

The correct option is D $\left(A\right)\to \left(i\right);\left(B\right)\to \left(iii\right);\left(C\right)\to \left)\right(ii)$

$\left(A\right)I{F}_5\to 5s^{2}5p^5$
Hybridisation: $s{p}^3{d}^2$
$\left(B\right)I{F}_{7}I\to 5s^{2}5p^5$
Hybridisation: $s{p}^3{d}^3$
$\left(C\right)Br{F}_3$
$Br\to 4s^{2}4p^5$
Hybridisation: $s{p}^{3}d$
